You have written a transaction in ABAP and now you want to find which z table it is associated with. In order to find this table, you can look in the DD02L table, which contains global settings, and the list of table fields. The DD03L table also contains detailed information about each field. There are many other tables describing a particular table field.
ABAP uses a hidden field to find a z-table
There are many times when you need to find a z-table, but you’re not sure which one to use. In these cases, ABAP will use a hidden field. This type of field is stored in memory in the same structure as the table. This hidden field will help you filter out the records that aren’t related to the one you’re looking for.
The SELECT statement is very similar to the standard SQL SELECT statement. It will allow you to query a table without changing the underlying database. It is also possible to modify a table using an ABAP program. The SELECT statement allows you to access data held by either Microsoft SQL or Oracle databases.
ABAP uses Open SQL statements to add data to a z-table
An ABAP program adds data to a z-table by using an Open SQL statement. This SQL statement contains a header record. This record is held in memory and has the same structure as the table. However, the ABAP object does not support the header record as a table name reference. Therefore, it is essential to understand the differences between these two types of SQL statements and their purpose in an ABAP program.
Open SQL is a set of ABAP statements that map the functionality of SQL to a centralized database in the R/3 system. ABAP programs written in Open SQL have a uniform syntax that will work in all supported SAP database systems. In addition, ABAP programs can be used with any R/3 System, even if the database system is not a SAP database. However, Open SQL statements can only be used with database tables that have been declared in the ABAP Dictionary.
ABAP creates a custom transaction for maintaining a z-table
In the process of maintaining a z table, ABAP creates a custom transaction. This transaction has two roles: maintenance and table view. A ztable has a number of fields and a large overview window is needed. The new table is assigned to a user who has access to it. The user can then use the Z transaction to perform maintenance on the table.
The custom transaction creates a new row to record the change. It also updates the underlying table with the new row. The table has a column for the new row, which is called Component. If the new row contains a row that has a duplicate value, the row is deleted. Similarly, deleting a row can cause the data to become corrupt.
The ABAP custom transaction creates a new row and column in a table. This is usually easier to customize than creating a custom table maintenance dialog. The process of creating the custom table maintenance dialog is often complex, but if you use the SAP standard, it should work just fine. The documentation on creating a custom table maintenance transaction is available in the SAP Library – Create a Custom Transaction
